I need new headphones for my ipod i love rock and dance music i am looking for over the ear and in-ear both types. what do you all sugest. price does not matter.
It's going to be hard to find good advice on headphones on the ultra-high end because most people can't afford one pair, let alone enough to compare and see what works for them. My guess is that most people here have only tried a few pairs and are just suggesting whatever they own.
If I wanted noise cancellation and/or something to take to the gym I would get in-ear monitors, if I wanted generally good sound when in a quiet room I would get open headphones ("audiophile"), and if I wanted to monitor (edit) sound I'd get closed headphones ("monitors")... Past that point, it's personal preference, mostly.
I've owned (and liked) a few low and mid-end headphones: the Sennheiser HD280, which have boring but highly accurate sound; the HD497, which have good bass but are a bit tinny; the Grado SR80i, which are very inaccurate but make bad recordings and really dense recordings sound good and warm; the shure e4, which sound good and block tons of noise; the ultimate ears 10, which sound slightly better maybe and block lots of noise?
They all sound fine to me. None sound great all the time. Anything that's well-liked and higher end than those (none of what I posted above is very fancy; I always get cheaper stuff since I break it so fast) should sound good, but at that level it's all application-specific. You're paying a lot of money. Make sure you're getting what you want... I've tried other comparable models, too (Sony, Audio Technica, Sennheiser, Grado, etc.) and they all sound good in their own way. (I have a sneaking suspicion Grados have the worst sound quality but they sound subjectively really good, it's weird.)
Best for the money are JVC marshmallows and Sony V150s... It's all depreciating returns past that point.
